## Description

Calculator 1005 brings back the scientific pocket calculator of the 1970s: a beige case, a seven-segment LCD with its mode indicators and the keys you remember — including the orange 2ndF layer that gives every key a second job.<br><br>It does not just look like the original, it behaves like it. Operators never show partial results; the whole formula is evaluated when you press =, with proper operator precedence and parentheses. The classic hardware tricks work too: 5 + = gives 10, pressing = again repeats the last operation, and an error locks the calculator until you press C.<br><br>Features<br>• Trigonometry in degrees, radians and grads<br>• Logarithms, powers and roots, π, x², 1/x, √x, ∛x, n!<br>• Numbers up to 10^±99 with EXP entry and the F⇌E switch between fixed and exponent display<br>• Memory registers M, A and B<br>• Statistics mode: enter data points and get n, Σx, Σx², mean and both standard deviations<br>• Everything stays where you left it — registers, statistics data and the display survive a restart<br><br>No ads, no accounts, no tracking, no internet access. The app requests no permissions at all.
